are ball mills used as a primary crusher

ASARCO » Milling

The primary crusher may send the crushed ore on to a secondary crusher or pile it directly onto the coarse ore stockpile. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The
